python - Django 属性错误

Question

我在 Django 项目中遇到了问题。 Python 2.7、apache 2.2、mysql数据库； 这是models.py的代码

from django.db import models
from django.contrib import admin

class Item(models.Model):
    name = models.CharField(max_length=150)
    description = models.TextField()

    class Meta:
        ordering = ['name']

    def __unicode__(self):
        return self.name

    def get_absolute_url(self):
        return 'item_detail', None, {'object_id': self.id}


class Photo(models.Model):
    item = models.ForeignKey('Item')
    title = models.CharField(max_length=100)
    image = models.ImageField(upload_to='photos')
    caption = models.CharField(max_length=250, blank=True)

    class Meta:
        ordering = ['title']

    def __unicode__(self):
        return self.title

    def get_absolute_url(self):
        return 'photo_detail', None, {'object_id': self.id}


class PhotoInline(admin.StackedInline):
    model = Photo


class ItemAdmin(admin.ModelAdmin):
    inlines = [PhotoInline]


admin.site.register(Item, ItemAdmin)
admin.site.register(Photo)

当我尝试在管理面板中创建对象项时，出现错误

遇到这个错误我该怎么办？

我刚刚在我的一个项目中尝试了您的代码片段，它的工作就像一个魅力，我没有看到任何问题，您确定吗，您仍然收到此错误。如果是这样，请检查您的数据库并查看您在设置文件中为媒体设置了 python 路径。
